Description: On March 13, 1997, while looking skyward for a glimpse of the Halle-Bopp Comet, thousands of Arizona residents also witnessed a mile-wide, V-shaped formation of lights slowly and silently gliding over their heads. ABC, NBC, CNN, MSNBC, The Discovery Channel and USA Today were just a few to report on the story. UFO buffs call it "the most documented mass sighting ever recorded." The official explanation is that the lights were flares dropped by military aircraft. Many experts and witnesses insist that what they saw were definitely not flares, but something beyond this world. Forty-four credible eyewitnesses, scientists and experts give compelling testimony to the reality of these mysterious visitations. The documentary is based on the book 'The Phoenix Lights -- A Skeptic's Discovery That We Are Not Alone' by Lynne D. Kitei, M.D., who appears in the film.
